Title: Gas detector
Inventor: MATSUOKA YOSHIHIRO
IPC: G01N27/12
Filed: 1990-02-14
Abstract: PURPOSE:To provide the gas detector which is less deteriorated by a secular change by setting the spacing between an anode and a cathode at >=0.5 times the max. thickness of a gas sensitive layer existing between the electrodes. CONSTITUTION:Electrode patterns 16 are formed on a ceramics substrate 12. The spacing W between the anode side electrode pattern 16a in contact with the gas sensitive layer 24 and the cathode side electrode pattern 16b of these electrode patterns 16 is formed to >=0.5 times the max. thickness (h) of the gas sensitive layer 24 existing between the electrodes. The current density near the electrode boundary of both electrodes is decreased by specifying the distance between the electrodes in such a manner and, therefore, the migration is suppressed and the increase in internal resistance is suppressed to a lower level. The deterioration of the electrodes in an oxidation atmosphere of a high temp. is, therefore, prevented and the exact taking out of the electric signal corresponding to the partial pressure of the gas is possible. In addition, the improvement in the durability of the gas detector is made as well.

Abstract: PURPOSE:To automatically set a work coordinate system in an on-line method by providing a copying route setting means which defines the intersecting line between a work subject surface and a plane decided by the start point, the end point, and the bypass point of the copying work as a copying work route. CONSTITUTION:A copying route setting means 18 sets an intersecting line lbetween the surface of a subject 4 and a plane phi decided by a start point T1, a bypass point T3, and an end point T2 of the copying work as a copying work route. Then a robot arm 1 is moved. A unit vector (n) of a work coordinate system is decided from the direction of the contact force which is detected by a force sensor 2 attached to a probe 3. Meanwhile a unit vector (a) of the work coordinate system is decided in parallel with a direction vector (m) of the intersecting line l between the plane phi and a contact plane II set at the point T1. Finally a 3rd unit vector (o) is decided as an external product of both vectors (a) and (n). Thus the work coordinate system is automatically set in an on-line method and the surface of the work subject having an unknown shape is smoothly copied.

Title: Focussing apparatus of microscope
Inventor: TOSHIMITSU KUNIO
IPC: G02B21/26
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent the contact of an objective lens and a sample and the liquid sticking to a dry system objective lens by controlling the position of a motor-driven focussing mechanism in accordance with whether the objective lens in an optical path at present and the objective lens which enters the optical path after it are a liquid immersion system or the dry system. SOLUTION: When the objective lens 41 which is in the optical path at present is the dry system and the objective lens 42 which enters the optical path after it is the liquid immersion system or the objective lens 42 in the optical path at present is the dry system and the objective lens 42 which enters the optical path after it is the dry system, a control circuit controls the position of the motor-driven aiming mechanism to the position where they are respectively saved for the portion of prescribed quantity in a direction where a stage is separated from the objective lenses 41 and 42 rather than the focussing position corresponding to the objective lenses 41 and 42, which comes into the optical path next.  Therefore, when change-over is executed from the dry system objective lens 41 to the liquid immersion system objective lens 42, a sufficiently wide interval is formed between the objective lens 42 and the sample 5. When change-over is executed from the liquid immersion system objective lens 42 into the dry system objective lens 41, the sufficiently wide interval is formed between the objective lens 41 and the sample.

Title: Fuel pump control device for engine
Inventor: HAYAKAWA MOTOO
IPC: F02M37/08
Filed: 1993-01-29
Abstract: PURPOSE:To prevent reduction of evaporated fuel quantity by renewing a changeover control region on the basis of the operation state at the time when actual fuel supply quantity is in shortage, as compared with the demand quantity in forced changeover from high to low rotation of a fuel pump, and thereby maximizing a pump operation region on the low rotation side. CONSTITUTION:When an operation state detection means detects the operation state of an engine, a rotational frequency changeover means receiving the detection signal changes over the rotational frequency of a fuel pump in a specified changeover control region regulated by the operation state. On the other hand, a forced changeover means also receives the output of the operation state detection means, so that it changes over forcedly the rotational frequency of the fuel pump in a specified decision region regulated by the pump operation state to the low rotation side. However, in the case when the fuel supply shortage state deviating from the demand fuel supply is detected by a supply shortage state detection means, a changeover control region renewal means renews the operation region of the engine when the fuel supply shortage state is detected to a changeover control region, when the forced changeover means is actuated.

Title: Dry type developing device
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/06
Filed: 1979-03-23
Abstract: PURPOSE:To correct the fluctuations of the charge amount of toner and stabilize developing action for a long period of time by applying a bias voltage which is neither ground potential nor developing bias potential to at least part of the developing device in contact with the developer at the time of performing dry-type developing by the friction-charged developer. CONSTITUTION:In a developing device 29, a nonmagnetic sleeve 8 is installed to the outside of the magnet roller 7 fixed to the body 6 of the developing device cotaining two-component developer 9. The developing bias voltage 60 to be applied to the sleeve 8 is voltage divided by resistances 60 and 61 and is applied to the housing 6 insulated from the body. Or the housing 6 and body are insulated and are grounded by way of a switching circuit 67. The developing bias voltage 60 is applied to the sleeve 8. Since the charge amount of the toner may be maintained at a constant value over a long period of time by these means, the good image similar to that at the initial time may be obtained even after multiple copyings.
